To all whom it may concern:

Be it known that I, MELVILLE E. Parana, a citizen of the United States of America, Denver and State of Colorado, have invented a new and useful Machine for Gumming Blanks for Covering Boxes and for other urposes, of which the following is a specification.

My invention relates to a new and improved mming machine for gumming blanks paper, fabric, leather, and other materials used for outside finishing coverings for paste board boxes and for'various other purposes in the box making and in other arts.

My invention, however, has been especially designed to gum paper blanks and blanks of other suitable materials that are used to cover pas e board boxes of various kinds and sizes, with the object of giving to the paste 'boardboxes a finished and artistic appearance; and the objects of my invention are:

First. To provide means for completely coating one s1de of a sheet of paper, fabric, or other material a suitable for covering boxes.

Second. To provide means for gumming the entire su'rface'of a blank at one operative gumming cycle movement of the gum- Inin mechanism.

T ird. To provide means by which the blanks automatically start the gumming mechanism when they feed in proper relation and position tothe, gumming mechanism, and that will lock the mechanism and prevent its operating when the pa erdoes not feed into orderly osition to t e gumming mechanism. An

Fourth; To. provide means by which blanks afterbeing gummedare spread out flat and straight at the discharge end ofthe machine. 7 A

other suitable fOlIIldH-tlOIL' These essential, ployed to feed the blanks to my gumming machine. In this res t, however, m invention contemplates roadly the use 0 any suitable blank feedin machine or device for automatically feeding the pa er or other material blanks from a stock of lanks on a table portion or from another machine to my improved gumming machine; and I have illustrated on one end of my blank machine a blank feeding mechanism which I preferably'use in connection with my blank mming. machine, and which feeds the b anks to the mechanism that carries them one at a time in successive order in proper relation to the gumming rolls, and which is a necessary part of my mmin machines mechanism. Likewise it is essential that means be employed to feed blanks after they have received a coating of adhesive gum material, such as glue gum, away from the-gumming rolls, and I have illustrated means for feeding the gummed blanks to a predetermining point,beyond the umming rolls, where they may be removed automatically operatin ma-- however, that some 'meaiisdie iein-fjj it, as well as the particular automatic feeding mechanism I preferably use, will form the subject-matter of separate applications for atents.

T e standards 1' and 2 are secured and connected together by cross tie castings 3,

which are bolted to the standards near the ifoot ortions 4 thereof. Between the stand:- ards place two gum holding pans ,5, which are placed on o tudinal center 0 the machine. The inner edges of these glue pots are distances from the longitu inal center of the standards, and they extend across bea tween the standards and rest'on and are,

posite sides of the longilaced at equal 1e5- bolted to shelf brackets 6, which are formed.

Each gum pet is provided with a set of three gumming. rolls 8 alikia.

The roller 7 of each. set of rollers is pro-,

vided with trunnions that are mounted in open sided journal bearings that are formed 10, the lower ends of which-are pivotally secured to the gum pot, by screws 11, see Fig. ,7. These 7 are adjustable with respect to the rollers gum pot, and

their. inner endsbear against the bearm of the arms -10-and they are held in ad]usted positionselg butterfly check 'nuts 14, which bearing arms 10, with the rollers. I

8 by means of threaded rods 12 that are. threaded tolugs 13, that are formed on the" the rods and 1 10 and 9, the sets of rolls being exactly 11-5. in the upper ends of pairs of swinging arms 9 .readily be withdrawn from the a ertui'ed standards.

ends of the yoke frame, and also mm the he journal bearings 16 consist of square blocks that are adjustably mounted. in slideways 20, formed in the yoke frame, by means of screws 21, that permit the journal ends of the rollers 9 to be moved and adjusted to cause the rollers 9 to bear evenly and to feed gum evenly to the op- I posite sides of the blanks, as they are fed upwardly between these rollers 9, by a plunr' so ger platen 22.

The normal space between the rolls 9, is the sameas the thickness of the platen 22, so that when the platen passes up be'-.

tween them, with a blank folded midway of its area over the edges of the said platen, the vertical portions of said blank, or the outer faces of the parts thereof lying against the sides of the said platen, contact with the rolls 9, and thus receive a coating of gum, which is evenly distributed over the contacting parts of the said blank. As the platen reaches the limit of its upward movement, the frames 17, are swung outward a short distance, so as to move the rolls 9 out of contact with theblank, which is immediately removed fromthe platen, in a manner to be hereinafter described, and the frames 17, 'are held in this position until the platen' dropsto its normal position, and as the rolls 9 are out of contact With the platen, the said platen is prevented from becoming gummed. When the platen passes down and out from between the rolls 9, the frames 17 are permitted to assume their normal positions. The frames 17, are spread or swung apart to clear the platen, by means of a bar 23, which is slidably mounted upon the inner sideof the standard 3, (see Fig. 3). The

, upper end of this bar terminates in a short ri ht angled bend 24, the opposite edges of,

w ich are beveled, and when' the bar is raised, these beveled edges of the part 24,

are forced between the ,opposing slideway portions 20, of the said frames 17 and the' frames are thereby swung on their pivots, to increase the space between the rolls 9.

\ The bar 23 is raised by means of a lever 25,

the outer end of which is pivotally attached to the standard 3. About midway of its length,this lever carries a roller 26, which contacts with a cam 27 of suitable contour, which at a proper time rocks the lever 25 so as to raise its inner end which is pivotally connected ,to theupper end of a short vertical arm 28, the lower end of which is pivotally attached tr the lower end of the said lever 23, which i; thereby raised in unison with the lever 2b., The cam 27, is rigidly mounted on the power shaft 29, of the machine. Therolls 9 areheld in their normal positions by screw rods 30, which are threaded to the vertcal portions of straps 31, which are seem-1 id to the ends of the frames 17, adJacent to the standard 1. The inner ends of these screw rods bear upon the platen guide 32, a nd are adjusted to give the required space between the rolls 9, the ro s being held in their adjusted'positions by jinn-nuts 33, which bear against the straps-31 as will be readily understood by reference to Figs. 4 a nd 7.

The. outward move ment' of the frameslT is cushioned in the following manner:

Into thecentral pc rtion of eachframe is Y screwed a post 17, to whichis pivotally attached the inner rnd of a rod'17", the

outer end of which is slidablymounted in.

an upright 17, secured to the water inlet of 'the gluepot 5. A col .ar 17 is secured upon the rod by a set screw, a short distance from the upright 17, and between the upright and the collar 'is 1111 erposed an expansion coil spring 17", whit 1h surrounds the said rod. When the fram as 17 are thrown apart by end 24 of the bar 23, the shock is absorbed by the springs 17, and when the bar 23 is lowered, the ;prings 17 press the frames toward each (ther, until the ends of the rods 30 engage the guide 32 and thus define or limit the ir ner movements of the frames 17. The trl nnion centers. of the:

frames 17 are positio led in axial alinement with the rollers 8, consequently when the rollers 9 swing reciprocally in their operative movement relative to the blank carrying plunger and the blank, they are in gum receiving contact with the rollers 8. The mechanism that re :iprocally moves the platen up and down between the rollers 9, will be explained frlly hereinafter. The rollers 8 are each rotz tively driven by gears 34.0n their rear ends, that are driven by a train of gears and sprocket chain driven wheels, which will he presently described. The glue pots 5, are xormed with chambers 35, which are provit ed witha supply of water through inlets 36, and steamis passed through pipes 37, which extend around the chambers 35, their em ls passing out through apertures 38 in a rerr. ovable plate 39 which closes the front ends of the chambers 35. The pipe 37 heats tle water, which keeps the liquid glue gum in the glue pot of an than the rollers 7, and. pick up the glue :and the rollers 7 are rotated slower than the The rollers 8 are set lower in the glue pans rotate in t e gum, as is desired to supply blanks as desired.

The gum rollers-8 of each set are preferably brass rollers and are rotatably driven bypinions 40, which mesh with the gears 34, an

the rollers 9 to properly and evenly coat the are mounted on "stub shafts 41 that extend through the frame 2, and on their front ends near t e frame 1 they are also provided with gears 42, that mesh with larger gears 43 that are mounted on the front endsof the rollers 7. The rollers 9 are driven by gears 44 that are mounted on their rear .ends and mesh with the gears 34, on the rear ends of the rollers 8. Upon the opposite ends of these stub shafts 41, ears 45'and 46 tively are secured. hese gears 45 an 46 are operated by two idler gears 47, which are mounted on pins that are securedto the frame 2, the are 47 being in mesh with each other an with the gears 45 and 46 respectively.

sprocket wheel 48 is driven by a sprocket chain 49, that extends from it to a sprocket wheel 50, that is mounted on a shaft 51,

which I term' the supplementary shaft, which is rotatably mounted in bearings 52 that are formed on the frames 1 and 2. This shaft 51 is driven from the clutch controlled main drivi shaft 29, as presently described. ro

tion is transmitted from t e gears 34 and 44 through the medium of the idler gears 47, which are of the same'size.

The gears 44 are consequently rotated at .the

and drive their .roller 9 in the same speed same irection as the gears and 46 spectively.

' The gumming machines supporting frame f is extended'bjeyond the standard 2, b :upper and lower cross ties 53 and rear en standards 54. A power drivensha'ft 55 is journaled in boxes 56, at the rear end of the chine, and carries a worm pinion 57, which meshes with a'worm gear 58, on the dri shaft 29. This driving shaft is milk ed parallel with the sides of the frames an at right angles to the longitudinal lengthor axis of the g machine.

The sha 55 is provided with aspring controlled friction clutch 59and operating lever 60, the clutch being arranged to always be in closed friction gripping condition, ex 1 tends from .the sprocket wheel 73' to a cept when it is forcibly held in an unclutched condition by moving the operating lever to unclutch it.

The inner end of the shaft 55 s rocket wheel The gear 45 is driven b a, sprocket wheel 48, that is secured on a ub portion that extends from it, and this r .rotative mo-- gear 40 to the and be in a square wrench receiving portion, to

which a wrench may be applied to turn the machines mechanism to see that allrparts work in. unison before applying steady power to it. This shaft carries a r 61, which meshes with a tablymounted on a stu shaft 63 that is secured to an angular bracket 64, that is secured to the standard 54. A bevel gear 65 is also mounted on this stub shaft, and this bevel gear meshes with a bevel gear 66 that is mounted on a stub shaft 67 that is secured to the an led end of the bracket 64. A sprocket w eel 68 is secured to the side of the bevel ar 66, and a s rocket chain 69 connects t is s rocket w eel 68 with a 0 that is mounted on the aft 51. I vThe clutch 59 is provided with a belt re-v ceiving pulley P011310 71, by which it may be driven b -a connection with apulley on a motor drivenslfaft. My invention contemplates any other arrangement of power connections and transmittingmembers that may form parts of or be connected to either the auxiliar. or supplementary shafts.

wheel 76, and on the stub shaft 77 the other art 85 of this clutch is slidably mounted.-

e slidinghalf 85 of this clutch is featherkeyed to the shaft'77, and is rovided with a .hub'86 in which a oove 8 is formed, in which inwardly ang ed ends of the yoke portion of a rock lever 88 fit loosely. This rock arm is supported intermediate of its ends by a bracket 89, that issecured to the framel.

The lower end of this rock arm 88, ispivotally secured to one-end of a connecting rod 90 which extends forward and connects to a .lever 91 that is secured to a short shaft 92, that extends at right angles to the supplementary shaft 51. The object of the levers 88 and 91 and the connecting rod 90 will be explained hereinafter. l.

The bevel gear 74 meshes with a bevel gear 93, that is supported on a. stub shaft that is secured to a bracket 94 which is bolted to the standard 1. A gear 95 is rig- I idly secured on the stub shaft with the bevel gear 93 and meshes with an idler gear 96, which is mounted on a pin that is secured to" the bracket 94. The gear 96 meshes with a gear 97' that is secured on the adjacent end of a shaft 98, the opposite ,end of which is journaled in a bracket 99, which is secured adjacent to the opposite edge of the standard 1 from the bracket 94. Adjoining the gear 97 is a gear 100 on the shaft 98, which meshes with an idle gear 101', whichin turn meshes with a similar idle gear 102, which latter gear meshes with a gear 103, on the.

adjacent end of a shaft 104, which is journaled in the brackets 94 and 99.

The gear wheel 103, meshes with a gear wheel 105 on a shaft 106, the outer end of which is journaled in the bracket 94 while its inner end is mounted in a bracket 107,.

which issecured to the standard 1, about midway between the brackets 94 and 99.

The shaft 106, carries a gear. wheel 108,

which meshes with a gear wheel 109, on a stub shaft 110, journaled in the bracket 107, and the gear wheel 109 meshes with a gear wheel 111, on a shaft 112, which is mounted in hearings on the side edges of a glue pot 113, which is suitably supported above the feed table and in direct line with the path of the platen 22, the shaft 112, carries a to carry the blanks. up through and between' V 'the glue pot roller 114 turns in t e direction as will he presently resilient roller 114, preferablyrubber, the diameter of, hich corresponds to the pitch diameter .of the ear wheel 111, and is adapted to co: ivey iquid glue from thejpot; 113, to asimil r roller 115, on the shaft 110, 7g and the roller 115, contacts with a roller 116 ontheshaft 1* )6, and theroller 116, contacts with a roller l17,'*on the shaft 104, the arrange'ment of the gearing bein such that of t e arrow, Fi 10,while roller 117, the function of w 110 is to supply a coating of lueto the eel .tral longitudinal portion ofa lank, turns ii the opposite direction, or in. the direction rhich feeds the blanks into the so machine, the d iameter of the roller 117 being such that it cc ntactswith the blanks as they r i are drawn fro In the feed table into-the machine,rina manner. to be hereinafterdescribed. I

The glue po t 113, carries a scraper a, having central lat aral trunnions' b, which rest in bearings 0,. on the sidesjof the ot., The for ward end of the scraper is bifurcated and, straddles the :r'oller 114, and the transverse edge OfthQblilllICfltGd portion is adaptedto regulate the st pply of glue furnished by the 7 said roller. 1L screw :1, is pivotally con nected at its lc wer end to the rear end of the pot, and passes through a recess in the tail end e, of the icraper. A coil spring f, encircles the S01 ew between the tail and the part to which the screw is pivoted, and exerts an upward pressure on the tail, and a thumb screw y, is threaded upon the upper end of the screw and bearsupon the tail,

whereby the s :raper could be adjusted with respect to the. roller, to regulate the amount of glue furnis led .by said roller. a

The feeding of the. blanks, whether effect- 1195 ed manually or b'y automatically operated mechanism, is so controlled that a; blank cannot pass from the feed table into the machine, after the gripper,which is adapted to carry the bl: tl'lkS to a position immediately above the plat en 22, has started on its forward inoveme it. The mechanism for accomplishing tl is as well asother o erations connected witl the feeding of the lanks to H themachine, 1! arranged and constructed as follows: ()n he forward end of the shaft 29, are secured two cams 118 and 119. The outer cam 118 is arranged to rock a lever 120, which is rigidly secured upon a trans verse shaft I23, which is mounted in bear- .12.. a

ings 122, on t] 1e standard 1. The opposite end of the shai t 121, from the lever 120 carries a short le er123, to which is pivotally attached one endofa connecting rod 124,

the opposite ld of which connects with a 1:25

short lever 1 on the end of a shaft 126, which is supported adjoining the .lever in the bracket 99, and at its opposite end in a a. bracket 127,which is bolted to the stand.

ard 1. The inier end of this shaft, or that 13 end supported in the bracket 127 carries a bifurcated lever 128, the ends of which carry opposing pins, or projections 129 which enter an annularv which is slidab y mounted on a rod 132, which is slidably mounted in bearings 133, and 134, on the, bracket 127. Collars 135 and 136jare secured upon the rod 132, the

former acting, as an abutment for the slidable collar 131, while'the latter acts as :an abutment for one end of a coil spring "137, which surrounds the stem and is interposed between the saidslidable collar 131, and the fixed collar 136.

Arecess138, of suitable length, is formed in the rod 132,'of a depth equal to one-half of its diameter, the recess bein positioned between the collar 136, and the Tmaring 134. A vertical bearin 139, is formed on the bracket 127 which aring extends beneath the rod 132, where therecess 138 occurs. A

rod 140, is slidably mounted in the bearing 139, the axial center of said rod being in line with the axial center of the rod 132, the rods being at right angles to each other.

The upper .portion of this rod 140 is recessed for a suitable distance from its end to a: depth' equal to one-half of its diameter,

and the flat .face of this recessed portion bears against the corresponding flat face of the recess 138, in the rod 132.

A recess 141, is formed in the central portion of the rod 140, similar to the recess 138 in the-rod 132, and the upper shoulder of this recess normally rests upon the end of a tail 142, which extends from the hub of the bifurcated lever 128, and normally supports the rod 140 in its bearing 139, with its lower end slightly above the feed table 72, and in line with a hole 143, in a metal strip 144, which is securedto the forward end of the feed table, approximately half of its width extending beyond the edge of the said table. A curved paper guide 145, is

secured at one end to the bracket 127, and

its opposite end passes under the lower end of the rod 140, and far enough above the strip 144, to unit the blanks tobe freely -fed between t e saidguide and the table, the

free end of the guide having a recess 146, in line with the rod 140, and hole 143. The functions of the rod 140 will be hereinafter explained.

Centrally of the width of the standard 1, and' on the outer face thereof, is suitably secured a vertical guide bar 147, in which is slidably mounted a bar 148, the upper end of which extendsabove the guide and is T- shaped; the lowerend of the bar 148, carries a pin 149, which projects through a vertical slot 150, in the guide and to which the upper end of a link 151, is secured. The

lower end of this link is pivota'llyconnected to one end ofa rock lever 152, which is mounted centrally of its length upon the carries a roller which 1 ve 130 in a collar 131,

.vided wit in Fig.37, in

The opposite end of ferential edge of the cam the cam adapted to, normally de rose the roller en of the rock lever and aving a dep portion 153,'which at a predetermined time permits the said roller endto a-spnng 154 being with the floor or foundation upon which the machine rests which exerts a .continuous .downward pull upon the link and bar 148,

lever thecircumconnected with the link 151, and

and likewise upon that end of the lever 152,

to which the link is attached. The T-por- I tion of the bar 148 extends in the direction of the length of the machine, and to its inner end s pivotally attached one end; of a link 155, the opposite end of which is connected to the inner end of a horizontally disposed lever 156, the opposite end of which carries a roller 157, which is in line with the glue roller 117, and normally separated from 119, permits the bar-148 to be depressed by 156, and the roller 157 is raised and'acts to ress a blank assing between it. and the glue roller 117, in contact with the said glue roller, the said cam 119, reversing the movethe same by a slight space. .When the cam the spring 154, the link 155, rocks thelever ment of the bar 148, and consequently rocking the lever 156, to lower the roller 157, as the blank passes beyond the same, thereby to prevent thesaid roller 157-from contacting with the glue roller 117.

The up r portion of the bar 148,,is prov a hole 158, which normally registers with a corresponding hole 159, 111 the guide bar 147. A pin 160, extends into the hole 159, and its outer end is pivotally con u on one end of a shaft 162, which is mount- 1 1n bearin 163, on the standard 1. To the other en of thisshaft is secured a horizo'ntally disposed rod 164, to which the lower end of a connecting rod 165, is attached.

.The upper end of the rod 165, connects with a short lever 166, on the end of a shaft 167, which is mounted in hearings in the brackets 99 and 127. The end of the shaft 167, which is mounted in the bracket 127, carries a short arm 168, hav" a horizontally disposed pm 169 in horizontal line with the nected to a short lever 161, which issecured adjacent end of the rod 132. The outer end. of the T-portion of the bar 148, carries a stop plate 170, which, when'the said bar isin its elevated position, ro'ects sli tly above the forward edge of e eed tab e, as shown sition to engage the forward edges of blan the canned forwardinto the machine, the said stop plate being depressed by the downward movement of the bar 148, as the blank is gripped, thus permitting the said blank to a be carried forward.

0 as they are passed beneath. guide 145 in position to be gripped and Upon each rotation of the cam 118, the

, the said shaft 121, rocks the shaft 126., carrg lever 120 and the shaft 121, are rocked and the connecting arm 124 which is operated by in the bifurcated lever 128, which slides t r 132.

Prior to each slidin movement of the rod 132, a blank is passed forward against the stop 170, and as the lever 128 is rocked by its shaft 126, the tail 142 of said lever per mit's' the pin 140 to drop but the pin is I stopped by the portion ofthe blank which covers the hole a. 143 in the table, and as a result, the upper end of the pin, whichiengages the flat face of the recess 138, in] the pin 132, is engaged by the approaching shoulder :12, of the said recess in the sai pin 132, which is slid forward by the lever 128, engaging the annularly groovedcollar prevented, and the roller 157, is thus pre-' 131, on the said rod, and further'forward movement of the rod is thereby prevented,

and thecomplete movement of the lever 128,

is permitted by the sliding of the collar 131 on the rod 132, against the action of the spring 137, which restores the said collar to its normal position as the movement of the lever 128 is reversed, and the rod 146, is lifted to its normal position by the tail 142.

If, however, no blank is fed in against the stop 170, the rocking of the lever 128 per-' mits the rod 140 to drop down'until its lower end passes through the hole 143,.in the feed table when its upperend is' below the path of the shoulder as, of the recess in the rod 132, and the said rod 132, is carried forward until its end engages the pin 169, in the arm 168, on the shaft 167, which is thus rocked, the spring 137 being strong enough to withstand the thrust. Therocking of the shaft 167, raises the connectin arm 165,

which, through the medium of t e rod 164,

rocks the shaft 162, and its lever 161. The pin 160, connected with the lever 161, is thereby slid into the hole 158, of the bar 148, and downward movement of the said bar, under the tension of the spring 154, is

vented from contacting with the glue roller 117,- which would otherwise be the case.

The blanks are carriedforward to a position above the platen 22, in the following manner: ,7

The shaft 98, carrles a sprocket wheel 171, which is connected by asprocket chain 172,

with a sprocket wheel 173, which is carried by a shaft mounted in suitable bearin s 174,

j on the standard 2. Horizontal bars 1 5 and 176, which are secured at their ends to the standards 1 and-2, support the upper and lower laps of the chain so as to prevent sagaim of the same. -17 7 extends parallel with the bar 175, and ashort distance from the inner side of the same, and is also secured at its ends to the standards 1 and 2, inian suitable manner.

Upon the bar 177, is idablymounteda Another horizontal bar carriagein the form of a vertically disposed portion 178, 7th rough which the bar passes, and a horizor tally, disposed portion 179, which extends inward from the vertical portion,,and forms the stationary member of a gripper, the u per face of this memberbeing on the same plane as the upper face of the feed table. A rod 180, passes through a bearing 181, on the carriage, upon the inner portion of Whh h is rigidl a secured the moV-l able jaw 182, of'the gripper, which comprisesfa hub ti rough which the rod passes, and a horizontally disposed curved portion which terminazes in a flat gripping ed which is arranged to rest squarely upon t e stationary jaw L79. Rigidly mounted on the rod 180, betwei n the jaw 182, and the bearing 181, is a cam 183, of the form shown in Fig. 16, which is designed to engage the inclined face of a block 184, carriedby an arm 185,. which is sacured to the rear endof the T-portion of tie bar 148, when the carriage is in its blank gripping position, whereby the jaw 182 is swungaway from the jaw I 179, in order -;o recelve a blank, the said cam being also arranged to engage the inclined face of a block 186, carried by a! bracket 187, ,t( be presently describedby which the jaw 182, is again opened to release the blan k. A 0011 spring 188, en-

circles the outer portion of the rod 180, and

one end of the ipring is inserted in a hole in the carriage, while its other end is inserted in a hole in nu; 189, which is screwed upon the end of the rod, the tension under which .the sprin is held, serving to hold the gripper jaw rmly against this stationary jaw when not in engagement. with either 0 the cam-engagi ng blocks. The carriage is moved to its bank-gripping, and blank-releasing positioi s in the following manner:

Upon the up per end of the outer face of the carriage is pivotally secured a hook arm 190, the hook e id of which is forward of its a pivotal end, the hook extending downward from the. arm; At the lower end of the vertical portior of the carriage, a hook arm 191, is pivotally secured, its hook end being rearward of its pivotal end, the hook ex tending upward from the arm. Each of the hook arms have extended hubs, which space the llOOli arms from the side of the carriage.

These. arms are connected by a vertical -link 192, and the lower arm 191, has a depending tail 193, extending from its hub portion, which is adapted to engage a stoppin 194, at th& blank gripping position of the carriage, ar (1 a stop pin 195 at the blank releasing positi on of the carriage. One link of the chain 1"2, is provided with a laterally "projecting lug 196, which is adapted to engage the look of the arm 190, to move thecarriage fc rward,. and the hook of the arm 191, to move the carriage rearward.

the

207 expansion spring 210- is mounted loosely and bears at one end against the upper end of the lever and at its other end-against a'collar 211, which is adjustably secured on the, rod by aset screw. The

uxiliary shaft and the cam 204 tated steadily when the machine is being roand being timed to act in proper relation to the'blank feeding rollers and the belts, move a ward enough to clear the ends of the arms 202, which the blank always, does when it strikes these pins squarely, and this short partial rotative movement of this shaft and the lever 91moves the connecting rod to throw in the clutch part 85 and operates x the gears above mentioned to raise the plun-v geron the up-stroke of its reciprocal movement.

When, however, a blank reaches the limit? of its forward movement in such a crooked or canted or twisted condition from any cause whatever as to only strike against one of the dogs 203, the other dog that the edge 7 Y of the blank does not strike, will still block ing of glue by roller 117, as the blank started the end of its cooperating lever 202 of the shaft 92, andvthe'plunger operating mechanism'is not released, and the platens will not move up, although the cam and its cam' lever reciprocate as the auxiliary shaft 29 rotates, and as the cam rotates, its cam levermoves upward but has to slide on its rod 207, there- ,by compressing the spring 210 as the shaft 92 is blocked by the dogs 203, and the cam lever cannot moveit.

The plunger starts on the upward stroke of its reciprocal movement, and its guideway bar travels in the slots of the brackets 32,

and 81, at its front end and between the rollers 212 at its rear end, which are mount-- ed on the bracket 187, and as it moves upward it strikes the blank that is resting on supporting rods G upon-which it slides centrally of it. area between its edges, and as it moves upward between the rollers the blank folds against the sides of the platen and the platen carries it up between the rollers 9, which press of the platen smooth and evenly coated with gum, of theblank, or that part resting upon the of the platen having been given a coaton its forward movement.

The plunger or platen 22 consists of a I board, of wood or other suitable material which is slidably and reciprocally mounted between the frames 1 and 2, and up and downbetweenthe gumming rollers 9. The

Above this brackei there is another bracket 216 that is securel to the standard 1, and

that is provided with a T slot and to this bracket are secure( the upper ends of spaced steel strips 32. These steel'strips extend below the castin and their lower ends are secured to a simil ll bracket 217 that is secured to the ram 5, and in the outerend of which a similar 'I" slot is formed. These brackets-and the s lideway strips, 1 term the plungcris upper gpideway. This upper T slot guideway receives the plungers sup porting guide bar. The lower end of the plungcrs support ng guide bar is provided with a disk 218 that fits snugly into a dash pot cylinder 219 that is-provided with an air "ent aperture 220. This dash pot is secured to the floor 1 lrfoundation that the machine is on, which acts to automatically aircushionthe plung 51 on its downward stroke.

The opposite en (1 of the plunger platen is provided with a si eel bar 221, that is secured along and to its edge. The opposite sides of this guide bai are machined and form guideways for the guide rollers 212 that are rotatably support ed in'lug portions of thepoint in order to )ring the blank in position a to be gripped anl conveyed to aspreader, in a manner to be presently described, and while the mechanism that reciprocates 'the plunger does this, yet inasmuch-as there might be a little lost motion, owing to the several parts that cooperatively work to- I have, in order redetcrmined stroke of the p' aten to a point, provided an auxiliary 1ftingmecha- 'nism that engages portion of its up vardstroke, and carrles 1t the plunger at the end positively to the same point at each and everyone of This mechanism 5 s as follows:

Upon the upper edge of the platen 22, is I secured a suction box 280, comprising a hollow longitudinal metal member, the upper T edge of which'is provided with a groove 281,

: throughout its length; On each side-of this groove, there is a row of small holes 282, which form a communication between the chamber-238, and the atmosphere, a tube 234, I connects with the chamber and extends down 4 through the platen and to its lower end, is

secured one end of a flexible rubber tube 235, theother end of which connects with a vacuum pump 286, in the form of a finder having a piston to which is seen a rod 237, which connects with one'end of a lever 288, the other endof which is pivotally I connected to a support 289, attached to one of the side members 53, of the frame. The lever 238, is operated by a suitable cam 240, on the 29, which is arranged to raise the lever, and hkewise the pump piston, at r a redetermined time, whereby, the suction w 'ch is communicated to the box 280, causes the blanktotightly adhere to the top ofthe said suctlon box'as thesameisbro v into contact with the said blank by the upv ward movement of the platen, and the blank is thereby held against accidental movement or displacement while moved up between the rollers 9. The reverse mt of the lever 288, at the proper mstan' "3 dothe vacuum in the suction box, the
